Regional & Utility Approvals in Ontario
Comprehensive guide to Regional municipality approvals, development charges, water/sewer connections, and utility permits including Hydro One, Enbridge Gas, railways, and airports.
Understanding Regional Government in Ontario
What is a Regional Municipality?
Ontario has a unique two-tier municipal system in several areas. Regional municipalities (upper-tier) provide services like water/sewer, regional roads, and waste management. Local municipalities (lower-tier) handle zoning, building permits, and local roads. Both levels charge development charges and require approvals.
Upper Tier (Regional)
- • Water & Wastewater treatment/distribution
- • Regional roads (major arterials)
- • Waste management
- • Public health units
- • Regional development charges
- • Official Plan approval authority
Lower Tier (Local Municipality)
- • Zoning By-laws
- • Building permits
- • Local roads
- • Parks and recreation
- • Local development charges
- • Site plan approval
You Need BOTH Regional and Local Approvals!
In two-tier areas (York, Peel, Durham, Halton, Waterloo, Niagara), you must satisfy BOTH your local municipality (e.g., City of Markham) AND your Regional municipality (York Region). This means two sets of development charges, two pre-consultations, and coordinated approvals. Budget extra time and money for Regional processes.
Regional Municipalities
Development Charges Explained
What are Development Charges (DCs)?
Development Charges are one-time fees charged by municipalities to recover capital costs of infrastructure needed to service new development (roads, water/sewer, parks, libraries, fire halls, etc.). DCs are governed by the Development Charges Act. In two-tier regions, you pay BOTH Regional DC and Local DC.
When are DCs Paid?
- Regional DC: Usually at building permit issuance (some Regions allow deferral to occupancy)
- Local DC: Varies - some at building permit, some at occupancy permit, some allow installments
- Rate Freeze: DC rate is frozen at building permit application date (protects from rate increases during construction)
Typical DC Breakdown (Single-Family Home in York Region)
*Amounts vary by municipality, unit size (larger homes pay more), and dwelling type. Rates updated annually. Always confirm current rates.
DC Exemptions & Reductions
Potential Exemptions:
- • Affordable housing units (income-restricted)
- • Accessory apartments/secondary suites
- • Non-profit housing
- • Expansions under 50% of existing GFA
- • Agricultural buildings
Typical Reductions:
- • Apartments vs houses (60-70% less DC)
- • Townhouses (20-30% less than detached)
- • Intensification areas (some municipalities)
- • Brownfield redevelopment grants
- • Replacement dwellings (credit for demolished)

CRITICAL: Call Before You Dig!
Ontario law requires you to contact Ontario One Call at least 5 business days before any excavation. They'll notify all utility providers to mark underground lines (gas, electric, telecom, water, sewer, cable).
